How to get rust enum value in Python

[kpr-8]

Hi

I have a simple rust enum that I am exporting to Python

use pyo3::prelude::*;

#[pyclass]
#[derive(Clone, Copy, Debug)]
pub enum MyEnum {   
    ZERO = 0,
    ONE = 1,
    TWO = 2,
}

#[pymodule]
fn enums(_py: Python, m: &PyModule) -> PyResult<()> {
    m.add_class::<MyEnum>()?;
    Ok(())
}

How do I get the value of MyEnum.ZERO in Python?

print(f"{MyEnum.ZERO}")
MyEnum.ZERO

print(f"{MyEnum.ZERO.value}")
Traceback (most recent call last):
  File "/home/enums/test.py", line 5, in <module>
    print(f"{MyEnum.ZERO.value}")
AttributeError: 'builtins.MyEnum' object has no attribute 'value'```

Answering my own question - this seems to work

impl MyEnum {
    #[getter]
    fn value(&self) -> PyResult<usize> {
        Ok(*self as usize)
    }
}
